ATENT ATTACHMENT FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 7 01,056, dated May 27, 1902.

Application filed August 29,1901. Serial No. 73,655. (No model.)

To all whmn it may concern: Be it known that I, LOUIS F. KGESTER, J12, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Attachments for Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an attachment for regulating the length of time a lamp will continue to burn and then permitting it to be extinguished automatically; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical section through a lamp provided with an attachment according to this invention. Fig. 2 is a front view of the attachment. Figs. 3 and -1t are respectively rear and plan views of the attachment. Fig. 5 is a side view showing the parts of the attachment when separated.

A is the oil-cup of the lamp.

B is the wick-tube of its burner, which is provided with a corrugated wheel and shaft b for raising and lowering the wick.

O is the plug which screws into the top of the oil-cup, and c is a guard secured to the plug around the wick-tube.

All the above-mentioned parts are of any approved construction.

D represents two supporting-arms formed of spring-wire,which depend from the plug 0 and which have horizontal portions cl at their lower ends.

E is a wick-holder formed of a strip of metal, which has its upper and vertical portion 6 arranged in line with its lower portion 6. The middle portion of the strip of metal is bent double and is folded together, forming two horizontal portions f, of which the upper portion f is provided with sockets g at its edges, which overlap the edges of the lower portion f. These sockets g are slid upon the horizontal portions d of the said arms, so that the wick-holder is supported by the said arms. The arms spring apart slightly and prevent the wick-holder from slipping.

' The upper portion 6 of the wick-holder has flanges h at its side edges,which engage with the lower part of the Wick 7c and hold its bottom edge at any desired elevation in the oilcup. The lower portion e or gage-plate of the wick-holder is provided with horizontal lines on its face, which may be numbered, if desired, to indicate how many hours the lamp will continue to burn. When the bottom of the wick 7c is arranged opposite the 10 line of the gage-plate and the oil-cup is filled with oil, the lamp will continue to burn for ten hours and will then be extinguished automatically, because the oil will be below the bottom of the wick. The middle part of the wick is coiled upon the plate f between the arms D and the plate a, and the wick can be raised or lowered without changing the position of its lower end. The lamp is set to burn with the wick at a certain normal height which is foundto give the best light. I-I isa gage for adjusting the height of the wick. This gage consists of a plate which has its lower end connected to the wick-tube by a hinge t' and which has a bent portion t" for clearing the flange on thetop of the wicktube. The charred top of the wick is removed every day, and the wick is set with its top level with the top of the gage. Before the lamp is lighted the gage is turned back on its hinge, so that it rests againstthe guard out of the heat of the flame.

The lamp-wick is raised from day to day until the coiled portion of it has been all used up. As the nights increase or decrease in length the lower end of the wick is adjusted to make the lamp burn for a longer or shorter period. The attachment is specially adapted for sidings-lamps on railroads; but it may also be used in many other situations.

What I claim is 1. The combination, with alamp-burner, of a wick-holder which depends from the said burner and supports the coiled middle part of the wick clear of the oil, said wick-holder being provided with an upwardly-projecting member which holds the lower part of the wick stationary and permits its upper and middle portions to be raised and lowered, substantially as set forth.

2. The combination, with a lamp-burner provided with depending arms, of a wickholder which engages with the said arms and supports the coiled middle part of the wick clear of the oil, said wick-holder being provided with an upwardly-projecting member which holds the lower part of the wick stationary and permits its upper and middle portions to be raised and lowered, substantially asset forth.

3. The combination, with a lamp-burner provided with a wick-tube, of a hinged gageplate which projects to a prearranged extent above the top of the said wick-tube when zontal portions at their lower ends, of a wick holderv provided with flanges for holding the bottom end portion of thewick in position, a graduated gage-plate below the said flanges, and sockets for engaging With the horizontal portions of the said arms, substantially as set forth.

6. The combination, with a lamp-burner provided with depending arms, of a wickholder formed of a strip of metal having its middle portion bent double and provided with sockets for engaging with the said arms, said wick-holder being also provided with a gageplate and means for holding the bottom end portion of the wick against the said gageplate, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
